Compare the2025 Audi A3VS 2025 Genesis G70

The A3’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The G70 doesn’t offer pre-crash pretensioners.

Both the A3 and G70 have child safety locks to prevent children from opening the rear doors. The A3 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The G70’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

The Audi A3 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The G70 doesn’t offer a front passenger side knee airbag.

The A3 has a standard Secondary Collision Brake Assist, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The G70 doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Over 200 people are killed each year when backed over by motor vehicles. The A3 has standard backup collision prevention system that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The G70 doesn’t offer automatic braking for stationary objects directly to the rear.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the A3. But it costs extra on the G70.

Both the A3 and the G70 have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, available blind spot warning systems, rear parking sensors and rear cross-path warning.

The A3’s corrosion warranty is 5 years longer than the G70’s (12 vs. 7 years).

There are over 26 percent more Audi dealers than there are Genesis dealers, which makes it easier should you ever need service under the A3’s warranty.

The Audi A3’s engine uses a cast iron block for durability, while the G70’s engines use an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

On the EPA test cycle the A3 gets better mileage than the G70:

Regenerative brakes improve the A3’s fuel efficiency by converting inertia back into energy instead of wasting it. The G70 doesn’t offer a regenerative braking system.

To lower fuel costs and make buying fuel easier, the Audi A3 uses regular unleaded gasoline (premium recommended for maximum performance). The G70 2.5T requires premium, which can cost on average about 84.9 cents more per gallon.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Audi A3 higher (6 out of 10) than the Genesis G70 (4 to 5). This means the A3 produces up to 12.1 pounds less smog-producing pollutants than the G70 every 15,000 miles.

The A3 offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The G70 doesn’t offer an SMG or a conventional manual transmission.

The A3 has standard front and rear gas-charged shocks for better control over choppy roads. The G70’s suspension doesn’t offer rear gas-charged shocks.

The Audi A3 may be more efficient, handle and accelerate better because it weighs about 350 to 550 pounds less than the Genesis G70.

The A3 is 7.5 inches shorter than the G70, making the A3 easier to handle, maneuver and park in tight spaces.

The A3 has a 3461 lbs. towing capacity. The G70 has no towing capacity.

The A3’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The G70’s standard manually variable intermittent wipers have to be constantly adjusted.

Heated windshield washer nozzles are standard on the A3 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The G70 doesn’t offer heated windshield washer nozzles.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The A3 Prestige has standard headlight washers to keep headlight output high. The G70 doesn’t offer headlight washers.

The A3’s optional Park Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The G70 doesn’t offer an automated parking system.

Insurance will cost less for the A3 owner. The Complete Car Cost Guide estimates that insurance for the A3 will cost $725 less than the G70 over a five-year period.
